pull that wheel and take a look at you Kleenwheels disk. Dollar to a donut, it has scrape marks on it.

I tossed the one I had, made a terrible racket with new pads.

They must be seated properly on the wheel to avoid scraping, and tend to move around when you take the wheel off.

Check the wheel bearing clearance while you are at it, too.
